- Jomsocial System plugin
Please temporarily unpublish the system plugin and try the installation again. When the installation has completed you can re-publish the system plugin.
Alternatively, you can try the following solution if the above does not work or apply to you:
1.) Install Ninjaboard normally. When it hangs, navigate to another page in the admin panel.
2.) Unzip the Ninjaboard install zip locally. You should see a number of folders and files. One of the folders is called "packages", and inside this you will find a component and at least one plugin. Install all of them as you would any Joomla extension.
If you are not using any of the above extensions, or neither solution resolves the problem, please post in our forums for help.
